The world-famous alkali metal experiment. Forget about that cute little drop of sodium burning the water in your petri dish, those two metals are the real deal

  • This is Fake, Mythbusters Busted this.

  • This was staged. They planted explosives under the bathtub. They admitted it. Case closed.

    In reality, such a small amount of Cesium in such a large amount of water wouldn't even produce the explosion that Braniac staged for RUBIDIUM. It does definitely react violently in water, but in order for Cesium and Rubidium to blow up the bathtub as they did in the video, you'd need a much larger mass of those elements.

  • @RNACLunchbox huh

  • lol my teacher showed us this in class...little did he know it was fake >:)

  • No metal on Earth does that in amounts so small.

  • I dislike this stupid show, this is bad science at ts absolute worst.

  • Francium is really rare. So rare that science barely knows more than nine or ten francium particles that are floating out there in space...

  • @1stsmosh Yes, they're real detonations of C-4 explosive.

  • Francium is radioactive and is so reactive that it is almst impossible to find a pure sample as it reacts with other elements or just decays.

  • dear santa ...

  • This is not fake...this is all real.

  • There is only a couple onces of Francium in the whole world, and the most stable isotope has a half-life of 22 mins, and its actually less reactive than cesium.
